Jordan Lyles (2-4) allowed two base runners — a single by Dansby Swanson in the first and another by Culberson in the second — before Culberson’s third homer made it 1-0 in the fifth.
Lyles turned in a solid performance after entering the game 0-1 with a 6.35 ERA in three career starts and one relief appearance against Atlanta. He gave up five hits and struck out six in his best outing since pitching 7 1/3 scoreless innings against Colorado on May 15.

Jose Pirela doubled to begin the game and advanced to third before Newcomb struck out Christian Villaneuva and Franmil Reyes. That was the only trouble he faced.

Padres: RF Wil Myers, sidelined 44 games with a strained left oblique, has gone 2 for 8 with one RBI in two rehab games with Triple-A El Paso. Myers, who hit a combined 58 homers the last two years, might return next week. “Body feels good, timing is probably a little bit off, but no red flags,” Manager Andy Green said. “Nothing bad. He’s scheduled off today and he’ll be back at it tomorrow.
Braves: LF Ronald Acuna Jr. ran the bases vigorously before the game and told manager Brian Snitker immediately afterward that he was “ready to go.” Acuna has been sidelined since May 28 with a sprained left knee sprain and bruises to his knee and lower back. He will likely begin a rehab assignment on Monday. … RHP Mike Foltynewicz was placed on the 10-day disabled list with triceps tightness. After Foltynewicz threw a bullpen session Saturday, the team decided to give him extra rest in hopes of bringing him back next weekend. Foltynewicz left his last start early after pitching five scoreless innings earlier this week. The team hopes he returns next weekend.
Padres: Green has yet to announce a starter for Sunday’s series finale.
Braves: RHP Julio Teheran has been reinstated from the disabled list and will make his 14th start this season and 10th of his career against San Diego. Teheran missed over a week with a sore thumb. He is 0-3 with a 6.14 ERA in his last four starts.
